Abstract: 1,062,608. Transistor generating and amplifying circuits. GENERAL ELECTRIC CO. Ltd. Oct. 1, 1965 [Oct. 14, 1964], No. 41929/64. Heading H3T. [Also in Division G3] The collector current of a transistor is stabilized by biasing it by means of a Zener diode to which a constant current is applied. In a generator comprising a transistor 3 acting as oscillator, controlled by piezo-electric crystal 7 and feeding into an amplifier comprising transistor 16, the base-emitter bias of transistor 3 is obtained from Zener diode 21. The collector current thus stabilized flows through resistor 10, so producing a stabilized base-emitter bias for the transistor 16. The collector current thereby stabilized flows through Zener diode 21. In a modification (Fig. 2, not shown) thermal stability is additionally obtained by replacing each of the transistors by a pair sharing a common emitter bias resistor network, the additional transistors serving for temperature stabilization; in addition, in this embodiment, the amplifier is followed by a direct-coupled emitterfollower stage and a further amplifier in common emitter connection.

[Also in Division E2] Actuating means for a door fastening mechanism comprises an attachment member 10 adapted to be secured to a door, and a handle 14 pivotally mounted on the attachment member and adapted to be operatively connected to a door fastening mechanism, the handle 14 being provided with a shank 13 projecting through the member 10, and the shank being formed with a transversely extending passage in which a bolt 16 is slidably mounted, there being also provided a sleeve 18 into which the shank extends and which is adapted to be operatively connected to the door fastening mechanism, and key-operable locking means 15 arranged on actuation to move the bolt between an operative position in which it projects from one end of said passage and engages the sleeve so that the latter is angularly movable with the handle and an inoperative position in which the sleeve is rotatable relative to the handle. As described, the locking means 15 is a cylinder lock, one end of the cylinder of which has a pin- and-slot connection with the bolt 16 which latter is adapted when in its operative position to engage with one of two diametrically opposite holes in the sleeve 18 depending upon the hand of the door. When the bolt is in its inoperative position the handle 14 is held in a " rest " position by a spring clip 17, Fig. 4, having projections 17a which pass through axial slots 12a in a boss portion 12 of the member 10, and engage in diametrically opposite grooves 13a in the shank 13.

Abstract: 1,026,956. Forming sheet material. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. Oct. 16, 1964 [Oct. 18, 1963], No. 42342/64. Heading B5A. A container, having exactly parallel side walls, is pressure formed from heat-softened thermoplastic sheet 10 upon a parallel sided male mould or plug 40, the upper part of the formed container being cooled more slowly than the bottom region thereof so that stripping of the container during the cooling is facilitated by virtue of the taper imparted thereto. The sheet is first partially drawn into a female mould member 30 (see Fig. 2, not shown) the plug then being lowered and the sheet formed there against by connecting the mould 30 to a source of pressure, as illustrated in Fig. 3 (not shown). A grooved rim (see Fig. 8, not shown) is formed about the container by a cooled ring 42 which co-operates with a complementary shoulder 38 on the female mould, the ring 42 being vertically adjustable upon the plug so that in co-operation with a vertically adjustable apertured bottom plate 33 of the female mould, a container of any required height may be formed. Mould 30 carries a bleed valve 36a, preferably located below plate 33, which opens when the pressure in the female mould exceeds a certain value, thus forming a stream of cooling air which hastens the cooling of the lower part of the container relative to the rim portion which is not contacted by the stream. The plug itself is cooled by suitable channels therein.

Abstract: 1405663 Cutting glass sheets PILKINGTON BROS Ltd 13 Sept 1973 [20 Sept 1972] 43621/72 Heading C1M In a method of cutting a strip of glass from a sheet by scoring and subsequently breaking open along the score line, the glass is treated either before or after scoring to modify the stress pattern so that a line of tensile stress is produced between the cutting line and the sheet edge. Preferably the modified stress pattern passes into compression between the line of tensile stress and the cutting line (Fig. 4). The stress modification is achieved by controlled local heating and/or cooling. For example as shown in Fig. 12 while a glass ribbon is being conveyed through an annealing lehr the edges are heated by gas burners 22 and subsequently cooled using atomized water/air sprays 23. Fig. 13 shows an annealed ribbon being cooled at its edges using a container 31 which is either packed with solid CO 2  or has liquid H 2  flowed through it. In a third embodiment (Fig. 11) a glass ribbon which has been scored transversely is moved intermittently so that the score lines are held stationary over perforated tubes 43 for up to 30 sees. Cooling air is directed on to the sheet from the tubes.

Apparatus for cleaning the sealing surfaces of coke oven doors or door frames comprises a supporting frame equipped with reciprocating cleaning tools 3 which are resiliently urged against sealing surfaces 6, each cleaning tool having a pair of scrapers 4, 5 the leading one of which is operative and engages the sealing surface, the trailing scraper being withdrawn from contact with the surface but engaging it on the return stroke. The scrapers 4, 5 are fast with plates 10 which are connected by a pivot pin 11 to a rod 12 which is urged towards the surface 6 by a spring 16. Rod 12 is axially slidably mounted in a crosshead 20 which is pivotally connected to links 21, 22 which are pivoted to the supporting frame. Link 21 is oscillated by a reversible motor and causes reciprocation of the crosshead 20 and scrapers 4, 5. The drag on the leading scraper rocks the plates 10 about the pivot pin 11 to raise the trailing scraper out of contact with the surface 6 so as to prevent re-deposition of matter thereon. Relatively resilient parts 7, 8 of the scrapers 4, 5 engage an edge 9 of the sealing surface.
